Coffee maker

Abstract

The invention discloses a coffee maker. The coffee maker comprises a coffee maker main body, an upper abrasive disk, a lower abrasive disk and a powder channel; a bean containing cavity and a bean grinding cavity which is formed below the bean containing cavity and is communicated with the bean containing cavity are formed in the coffee maker main body, the powder channel is communicated with thebean grinding cavity, the upper abrasive disk and the lower abrasive disk are arranged in the bean grinding cavity, the coffer maker further comprises a heat source which is arranged on the coffee maker main body and an air tube which makes the heat source communicated with the bean containing cavity, and the heat source is used for heating the interior of the bean containing cavity through the air pipe; a plurality of blades are arranged on the circumference surface of the lower abrasive disk, and when the blades rotate along with the lower abrasive disk, negative pressure is formed in the bean grinding cavity so that hot airflow which passes through the bean containing cavity can dry the bean grinding cavity and the powder channel. According to the coffee maker, ground bean powder can bequickly conveyed to a brewing component through rotation of the blades, by matching with the heat source, the blades have the cleaning, high-temperature drying and disinfection and sterilization effects on the cavities and the powder channel where coffee beans and bean powder pass in the coffer maker, and the sanitation safety performance of the coffer maker is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a coffee machine. Background technique [0002] At present, the traditional coffee grinder in the prior art has moisture and accumulated water in the cavity after brewing coffee, which causes incomplete grinding of beans during the next work, and even wet and sticky beans, and even causes If the bean powder cannot be discharged, the whole machine may work abnormally, and in severe cases, the motor may be damaged, and the humid environment is easy to breed bacteria, which will affect health. [0003] In order to solve the above problems, the Chinese patent publication No. CN2606563Y provides a diversion and heat dissipation device for coffee grinders. The diversion and heat dissipation mechanism and a cooling fan are arranged in the device, so that the diversion path of the heat dissipation airflow can be formed in the machine base. To facilitate the removal of moist...

Problems solved by technology

However, due to the addition of a fan in this device, on the one hand, the cost of the device is increased; on the other hand, the operation of the fan and the bean grinding mechanism will not be automatically synchronized, and the operation of the fan needs to be controlled separately, which brings trouble to the operation.
